Lynne I tried your technique and discovered the mod that was causing the errors was my shoutbox.
I'm going to seek support from there website but I'll appreciate any advice from people on here too.
I found the shoutbox on here but eventually bought the PRO version to enable me to use all it's features.
Link to shoutbox LITE version on .org ==>
Inferno shoutbox LITE
Link to shoutbox PRO version ==>
Inferno shoutbox PRO
Thanks.
